Get Fuel and emissions control system -> Exhaust system Guide for Volkswagen Taos SUV First Generation (2022-2025)

Fuels can contaminate the environment. Collect any leaking operating ﬂuids and dispose of them according to legal

regulations.

Exhaust system

Introduction

The exhaust-relevant components reduce exhaust emissions:

Catalytic converter ⇒ Catalytic converter.

Particulate ﬁlter (depending on the vehicle equipment) ⇒ Particulate ﬁlter.

WARNING

If the engine runs in enclosed spaces, poisonous gases may enter the vehicle interior. This can cause serious injuries and

death due to asphyxiation.

Never start the engine in conﬁned spaces.

Do not allow the engine to run in conﬁned spaces.

Do not leave your vehicle unattended while the engine is running.

WARNING

The parts of the exhaust system become very hot and can ignite ﬂammable materials, for example shrubs, leaves, dry

grass or spilled fuel. This can lead to a ﬁre and cause accidents and serious or fatal injuries.

Never park the vehicle in such a way so that the exhaust system components come into contact with ﬂammable

materials under the vehicle.

Never use additional undercoating or corrosion protection for exhaust pipes, catalytic converters, heat shields, or

particulate ﬁlters.

and

Safety precautions for

To ensure that the exhaust system and the engine catalytic converter can work correctly for a long time, observe the following

Only refuel with fuel permitted for the vehicle.

Never drive until the fuel tank is completely empty ⇒ Refueling.

Never add too much engine oil ⇒ Checking the engine oil level and adding oil .

Do not tow-start the vehicle; use jump-start assistance instead ⇒ Preparing and Performing a Jump-start.

If there are engine misﬁres, loss of power, or poor engine operation while driving, reduce the speed immediately and have the

vehicle checked by suitably qualiﬁed professionals ⇒ Troubleshooting. Volkswagen recommends contacting an authorized

Volkswagen dealer or authorized Volkswagen Service Facility. Otherwise, uncombusted fuel could be present in the exhaust

system and then enter the atmosphere. The catalytic converter may also be damaged from overheating.

The exhaust may smell like sulfur when the emissions control system is running correctly.

and

Safety precautions for

Function

The particulate ﬁlter (depends on how your vehicle is equipped) ﬁlters out soot from the exhaust gas.

Regeneration

With normal vehicle usage, the ﬁlter cleans itself. If the ﬁlter is unable to clean itself, e.g. if you only make short trips for an

extended period of time, the ﬁlter can become blocked with soot. The particulate ﬁlter needs to be cleaned (regenerated).

Noises, light odors, and increased engine speeds may occur during the regeneration. The radiator fan may continue to run

while driving and after turning off the engine.

To assist in particulate ﬁlter regeneration, Volkswagen recommends avoiding driving short distances too frequently.

The soot in the particulate filter is burned periodically at high temperatures. The yellow

Safety precautions for

If the engine does not run smoothly and malfunctions

If the engine does not run smoothly or malfunctions while driving, it can indicate poor fuel quality.

1. Reduce your speed immediately.

2. Drive with a moderate RPM and low engine load to the nearest suitably qualiﬁed professional. Volkswagen recommends

contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

3. If these symptoms occur directly after refueling, stop the engine immediately to prevent subsequent damage.

Do not continue driving! Contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility for

assistance.

Particulate ﬁlter clogged with soot

The yellow indicator light turns on.

The particulate ﬁlter is clogged with soot and a regeneration is necessary.

Prerequisite for the regeneration drive: The engine is at operating temperature.

For gasoline engines

1. Drive at a speed of between approx. 50 km/h and 120 km/h (30 mph and 75 mph).

The resulting temperature increase burns off the soot in the ﬁlter.

2. Only end the regeneration drive once the indicator light turns off.

3. If the indicator light is still illuminated after driving for approximately 40 minutes, drive immediately to suitably qualiﬁed

professionals for assistance. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized

Volkswagen Service Facility.

If, during the regeneration drive, the prompt to refuel appears in the Volkswagen Digital Cockpit, the particulate ﬁlter

regeneration process can be interrupted.

Refuel if necessary and then continue the regeneration drive.

Automatic fuel tank ventilation malfunction

If the fuel tank is opened without prior ventilation, fuel vapors will escape from the ﬁller neck. This may lead to temporary

odors.

Opening the fuel tank without ventilation:

1. Press the release button

The fuel ﬁller ﬂap will release without ventilation.

2. Open the fuel ﬁller ﬂap.

Refueling with an automatic fuel tank ventilation malfunction:

1. Hold the fuel pump nozzle handle down to ensure optimum refueling.

2. Only continue carefully in this case until the fuel tank is full.

3. If the automatic ventilation process is still not working, contact a suitably qualiﬁed professional and have the ventilation

system checked. Volkswagen recommends contacting an authorized Volkswagen dealer or authorized Volkswagen

Service Facility.

The fuel pump nozzle may turn off prematurely when refueling due to the lack of ventilation.

Exhaust-related malfunction

The yellow

indicator light turns on.

An exhaust-related component is malfunctioning, which could damage the vehicle.

1. Contact a suitably qualiﬁed professional and have the engine and the exhaust system checked. Volkswagen recommends

contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

Misﬁre

The yellow

indicator light ﬂashes.

There is misﬁre which could damage the vehicle.

1. Contact a suitably qualiﬁed professional and have the engine and the exhaust system checked. Volkswagen recommends

contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

WARNING

Sudden braking or driving maneuvers, e.g. if an indicator light turns on or if the engine does not run smoothly, can cause

accidents. This can result in serious injury or death.

Always adapt your speed and driving style to the visibility, weather, road and trafﬁc conditions.

Follow the road trafﬁc laws and regulations that apply in the country you are driving in.

If the indicator lights are on or flashing, it is likely that there is an engine malfunction and that fuel consumption will

increase.
